This invention relates to new and useful improvements in oil savers. V Iw One object of the invention is to provide an oil saver for use ondrill cable, rod and the like in connection with oil and gas wells,whereby certain advantageous results are ob tained.

A particular object of the inventionis to provide improved packing meansfor embracing a cable or other cylindrical member together with simpleand positive packing compressing means including elements working withsufficient leverage to exert ample pressure to quickly compress thepacking against varying head pressures.

A further obj ectof the invention is to provide a packing and a guidearranged for,

ready application to and removal from the cable or other verticallymoving member, and involving simple and easily worked parts.

Another object of the invention is to provide an oil saver having itsseal packing below its supporting flange, whereby the length of thedevice is shortened which permits the temper screw to be screwed furtherdown before reclamping a cable.

A still further object of the invention is to provide an oil saver inwhich the adjustable packing may be quickly and conveniently replaced. A

Another object of the invention is to provide a packing member ofpeculiar construc tion arranged to equally grip a cylindrical memberthroughout the length ofsaid pack ing member and having adjustable meansfor feeding said packing member to the cylindrical member as it wears.

Animportantobject of the invention is to provide an oil saver havingadjustable packing means of a minimum number of working parts of ruggedconstruction, thus providing for efficiency and speed in operation.

A construction designed to carry out the invention will be hereinafterdescribed together with other features of the invention.

The invention will be more readily understood from a reading of thefollowing speci- [ication and by reference to the accompanying drawingsin which an example of the invention is shown, and wherein Figure 1 is aside elevation of ran oil saver constructed in accordance with theinvention and illustrated as applied to a cable,

Inthe drawings the numeral designates a split housing. The housingincludes a re movable lower member 10' secured thereto by bolts 11 andnuts 12. The bolts 11 are mounted in flanges 13 extending from. areduced neck 14 of the housing. Suitable packing strips (Figure 4;) areinterposed between the housing members. I

The housing includes an upper packing chamber A immediately above thereduced neck 14, and a lower packing chamber B. A

ing against upright shoes 19. The shoes (Figure 16) have their rearfaces flat to receive the blocks and their front faces concaved toembrace opposite sides of a cylindrical packing member or sleeve 20fitting in the lower chamber.

Adjusting screws 21 (Figure 13) are threaded through the flange at thesame angles as the walls of the guides 17. Each wedge block 18 (Figures2 and 12) has a key slot 22 for receiving the lower end of one of thescrews 21, whereby the blocks are suspended in the guides. By rotatingthe screws clockwise the blocks are slid downwardly and inwardly thusdisplacing the shoes 19 inwardly and compressing the packing sleeveabout the cable, rod or other element which passes through the device.

The neck 14 has a reduced opening 23 through which the cable C passesand thus said neck forms the top of the lower packing chamber, wherebythe sleeve 20 is retained. The upper packing chamber A has cheek plates24 with opposite horizontal slots 25 for receiving and supporting lugs26 of followers 27. The lugs slide in the slots and have their outerends reduced and rounded to form pins 26 for the pivoting thereon oflinks 28 which have their opposite ends pivoted to levers 29. The leversare pivotally mounted on each side of the housing at the center of thecheek plates on screws 53. The links are pivoted to each lever onopposite sides of its center and so positioned that when each lever isswung upwardly the followers are drawn inwardly toward the center of thehousing and the cable G.

The followers 27 are provided with upright dove-tailed grooves 30 forreceiving therein a dovetailed rib 31 (Figures 9 and 11) of arectangular packing block or member 32 (Figure 8). The packing block isformed of rubber or any material suitable for the purpose and has aconcave vertical face or seat Grease pockets 33' may be provided in theface 33.

It is obvious that the inward movement of the followers will clamp thepacking blocks about the cable and by the location of the lugs 26 at thecenter of the followers 27 the inward pressure will be evenlydistributed to the packing blocks causing said blocks to antomaticallyadjust themselves for equal gripping of the cable throughout its length.

A removable guide block .34 is set into the top of the housing on thesame side as the removable section 10 and provides for the con- Venient,easy and quick application of the device to and removal from a cable rodor the like. The removable guide block 34 rests'on shoulders 35 of thehousing and has a tongue 36 (Figures 15 and 18) extending down betweenthe cheek plates to the top of the chamber A, thus forming a top guidefor the follower and packing. The shoulders and the tongue 36 areprovided with an opening 37 for the insertion of a bolt 38 there throughand on which a nut 38 is screwed for securing the block to the housing.

A guide roller 39 is mounted in a recess 40 of the block 34 on a shaft41 secured in said block. A similar guide roller 39 is mounted in likemanner in a recess 40 of the housing, directly opposite and inhorizontal alinement with the recess 40. Recesses 23 are also providedin the block and housing for the passage therethrough of the cable 0which is guided by the rollers into the housing.

Segmental gears 43 are mounted on the levers 29 and are swung by pinions44 fastened on the opposite ends of a shaft 45 journaled in a yoke 46extending laterally from the top of the housing. A Worm gear 47 isfastened on the shaft 45 Within the yoke. A worm screw 49 (Figure 2)meshes with and drives the gear 47 and is journaled on a stud 50 screwedinto the housing above the yoke.

A hold down keeper 51 secured to the yoke bridges over the hub of theworm screw 49 and a crank handle (Figure 1) 52 engages on the angularend of the screw for revolving the same'on the stud 50 and thusoperating the gears 43. The segmental gears each have their teethterminating so that when the pinions 44 engage in the uppermost teeththe parts will'be locked against further movement except in a reversedirection, thus holding the followers against accidental displacementfrom within the chamber A.

It is obvious that by revolving the crank handle 52 the shaft 45 isrotated and the segmental gears are swung and as they are swung thelinks pull the followers inwardly, thus compressing the packing againstthe cable C. After continued use and when the pinions reach thelowermost teeth on the segments, the packing will have been completelyworn out and further inward movement of the followers will be prevented.The open 110 ator will thus know that the packing must be replaced. I I

When it becomes necessary to replace the upper packing 32 it is merelynecessary to remove the screws 53 to displace the levers 29 115 and thelinks 28 thus leaving the followers free for removal from the housingand for renewing the packing in the followers. In replacing the upperpacking the parts are manipulated to bring the segmental gears to 120the position shown in Figure 1.

It will be seen that by reason of the worm gearing and comparativelylarge segments considerable leverage is had and therefore the levers 29will compress the packing 32 with 125 ample force. The device may beeasily and quickly operated and as it is only necessary to handle fivebolts (38, two 11s and two 53s) the saver may be quickly mounted ordismounted.

Various changes in the size and shape of the different parts, as well asmodifications and alterations, may be made within the scope of theappended claims.
